Multifunctional power line carrier concentrator

Abstract

The invention belongs to the technical field of power systems. A multifunctional power line carrier concentrator comprises a microprocessor, a power line carrier communication unit connected to the microprocessor, an external storage unit, an infrared communication interface, a power line coupling interface connected to the power line carrier communication unit, and a power amplifier circuit connected between the power line carrier communication unit and the power line coupling interface. The concentrator is characterized in that the concentrator further comprises a signal frequency acquisition module, an attenuation module, an AD sampling module, a signal processing module and a display module; the signal frequency acquisition module performs shaping processing on an acquired input signalto generate a frequency signal, and transmits the frequency signal to the signal processing module; the microprocessor is used for receiving the data information sent by the signal processing moduleand transmitting the data information to a TFT screen of the display module for display; and the display module is used for displaying the information transmitted by the microprocessor. The concentrator also has a signal detection function.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a multifunctional power carrier concentrator. Background technique [0002] The concentrator is the central management equipment and control equipment of the remote centralized meter reading system, responsible for regular reading of terminal data, system command transmission, data communication, network management, event recording, data horizontal transmission and other functions. The carrier concentrator is a general data device in the meter reading area. It can collect, process and store data from the collectors under its jurisdiction through the power carrier or RS485, and supports GPRS wireless or Ethernet to realize remote communication with the server. [0003] Power carrier concentrators, such as Chinese patent application number CN200610030615.4 (adaptive power carrier concentrator), generally include a microprocessor, a power carrier communication unit...

AI Technical Summary

Problems solved by technology

Since the signal received by the concentrator is not good, an amplifier is used to enhance it (power amplifier circuit), and the amplifier will affect the call quality of the three major operators of China Mobile, China Unicom and China Telecom
